Challenger CSM3800F Molded Case Circuit Breaker

Challenger CSM3800F Molded Case Circuit Breaker is a three-pole, 800 A, 600 V MCCB designed for heavy‑duty distribution in industrial and commercial panels. It uses an electronic LI trip mechanism for reliable overcurrent protection and is UL/CSA-listed with CE marking. This model sits in Challenger’s MDL-frame family and is cross-referenced in Eaton catalogs (often labeled CHMDL3800F or CMDL3800F), reflecting compatibility across the Challenger/Eaton MDL form factor. The device provides a short-circuit current rating of 65 kAIC at 480 VAC, enabling rapid interruption of high‑fault currents, while rated for continuous operation at the 600 VAC system level. With 3 poles and an 800 A rating, it serves as main feeder protection in sizable electrical installations and as branch‑circuit protection in machine rooms and distribution panels. Typical applications include industrial control panels, motor feeder circuits, and service entrances where a robust, code‑conforming MCCB is required.
